The Staff of Asclepius (Æsclepius, Asklepios), (Personification of Medical or healing Art and its
ideals). The traditional symbol of medicine, the staff of Asclepius with a single serpent
encircling a staff, classically a rough-hewn knotty tree limb.

Asclepius (an ancient greek physician deified as the god of medicine) is traditionally depicted as
a bearded man wearing a robe that leaves his chest uncovered and holding a staff with his sacred
single serpent coiled around it, symbolizing renewal of youth as the serpent casts off its skin.

Wadjet "the Green One", the serpent goddess of Lower Egypt from the Pre-Dynastic period
demonstrates the earliest known representation of a single serpent entwined
around a pole – in this case a papyrus reed.
